Practice Test Take the Practice Test on Blackboard!!!! More than half of the questions will be formatted the same or similarly as the practice test, quizzes and in-class problems Take the Emerge Practice Tests Questions may have different numbers, but the same concepts Questions may be the EXACT SAME

In This Review Session… We will go over: Key terms/concepts in EXCEL Functions in EXCEL Practice Test Questions

Syntax: =AVERAGE(number1, [number2],...) Arguments: number1 Required  The first number, cell reference, or range for which you want the average. number2,... Optional  Additional numbers, cell references or ranges for which you want the average, up to a maximum of 255.

Description: Returns the average (arithmetic mean) of the arguments. Remarks: Arguments can either be numbers or names, ranges, or cell references that contain numbers. Logical values and text representations of numbers that you type directly into the list of arguments are counted. Errors: Arguments that are error values or text that cannot be translated into numbers cause errors.

Microsoft ® Excel ® Mathematical Functions Syntax: =SUM(number1, [number2], [number3], [number4],...) Arguments: number1 Required  The first item that you want to add. number2, number3, number4,... Optional  The remaining items that you want to add, up to a total of 255 items.

Microsoft ® Excel ® Mathematical Functions Description: Adds all the numbers that you specify as arguments. Remarks: Each argument can be a range, a cell reference, an array, a constant, a formula, or the result from another function. If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, or text in the array or reference are ignored. Errors: If any arguments are error values, or if any arguments are text that cannot be translated into numbers, Excel displays an error.

Absolute, Mixed and Relative For a formula being copied: If the reference is:It changes to: $A$1 (absolute column and absolute row) $A$1 (the reference is absolute) A$1 (relative column and absolute row) C$1 (the reference is mixed) $A1 (absolute column and relative row) $A3 (the reference is mixed) A1 (relative column and relative row) C3 (the reference is relative)

Quiz Question Mac and Farva need 40 liters of cola for an upcoming frat party. They notice the two grocery stores near them have drastically different prices for liters. One grocery sells liters for $1.20 per liter. Another has a sale going on, “Buy 10 Liters of Cola for only $5”. Assuming they were going to purchase all 40 at the same grocery, write a formula that would calculate the potential savings if they choose the cheaper option. =( ) * 40 =(1.20- (5/10)) * 40

Helpful Hints Don’t forget an “=” when you are asked for a formula Rows VS Columns Trick Remember there are sometimes several correct ways to write the same answer! Do not ignore the Emerge content. It is a good portion of the test. Study Definitions. Retake the practice test and re-practice the homework this weekend
